FOUNTAIN-BRUSH.

Application filed March 7,

To all whom it may concern:

' Be it known that I, CHRISTOPHER A. GAR- VEY, a citizen of the UnitedStates of America, a resident of Cla ton, in the county of issouri, haveinvented certain new and useful Improvements in Fountain-Brushes, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification.

My invention relates to a fountain brush, the present improvement beingintended more particularly for use in brushes used for stenciling or forother purposes in which a to and fro movement is im arted to the brushwhile it is in service. y improved brush includes a pendulum or swingingvalve for controlling the flow of liquidfrom the brush reservoir, and aspring by which the movement of the valve is regulated during itsswinging motion, thereby preventing an excess flow of liquid past thevalve. The improvement also includes means for varye ing the tension ofsaid spring with consequent variance of its action upon the valve.

Figure I is an elevation of my fountain brush. 7

Fig. II is a longitudinal section.

Fig. III is a transverse section through the reservoir of thebrush.

In the drawings I have shown my brush in a form suitable for use withmarking stencils, but it will be understood that the brush may be of anysuitable type other than that shown. i

The reservoir A of the brush shown is intended to serve also as ahandle,and it has fitted to its lower end a discharge device B to which thecontents of the reservoir may be delivered to pass to the brush tip Cattached to the dischar e device: The reservoir A, the brush tip and thedischarge device B, in so far as their general features are con-'cerned, may be of any desired configuration or form.

At the end of the discharge device to which the reservoir A is attachedis a neck 1 fitted within the reservoir, and preferably provided with anexternal screw thread fitted to an internal screw thread in thereservoir. The neck 1 is screw threaded internally, as seen at 2. Saidinternal screw Specification of Letters Patent.

Patented Nov. 23, 1920.

and a pendent stem 7 of smaller diameter than the diameter of theorifice, the stem depending into the discharge device and being providedwith a weighted lower end 8, preferably produced by making the lowerportion of the stem of greater diameter than the portion of the stemintermediate of said weighted lower end 8 and the valve head 6.

Between the head 6 of the valve device D and the adjusting screw 3 is aspring 9, which may normally serve to hold the valve device so that thevalve head is in contact with its seat around the orifice 5, and whichacts to govern the movement of said valve device, so that when the valvehead is tilted from its seat on the web 4 it will be returned to itsseat and will also be prevented from excessive movement due to to andfro movement of the brush in use.

In the practical use of my brush it is moved to and fro, and during suchto and fro movement the pendulum or swinging valve device D vibrates sothatv the valve head 6 is first tilted in one direction and then in theopposite direction to permit flow of liquid through the dischargeorifice 5. The spring 9 constantly tends to limit the degree to whichthe valve is tilted, and the tension of this spring may be regulated atwill by adjusting the adjusting screw 3. Therefore any desired speed offlowof liquid past the valve head 6 may be acquired, and the desireddefinite rate of flow will be obtained during the use of the brush, forthe reason that the valve device will partake of only a given swingingmotion in accordance with the intended control.

I claim:

In a fountain brush, a reservoir, a discharge device secured to one endof said reservoir, said discharge device having a valve seat membertherein provided with a discharge orifice andhaving a neck extendingfrom said valve seat member, an adjusting screw movable in said neck apendulum valve device suspended from said valve seat member at thelocation of said discharge orifice, and a spring interposed between saidvalve device and said adjusting screw. 10

In testimony that I claim the foregoing I hereunto afiiX my signature.

CHRISTOPHER A. GARVEY.
